Wow, your the guy I need to talk to. I am looking at doing an 8XA card setup. I gather from your video you get something close to 1 lpm at the 5A setting? Was this a 12v DC reading? I run conventional electrolysis with electrolyte and get about that around 15A. Ideally I would like about 2 lpm, but I don't want to run 30A thru my car electrical system. I gather you need a coil in the setup. Do you have a schematic? Where can I get some of the details using the 8XA? The 8XA takes 12v AC, correct? Is that Tony's card you are using?
